Thank you. Let me ask a question regarding this, as I feel now that I am
not that professional in CORBA.
You are right, we will have CGIs running on different web servers. Is it
enough, then, to have an object on every web server which simply routes
the asks to the correct object in the background, and gives back the
answer of that object? Or something more sophisticated is needed on this
I saw some proxy objects generated in the stubs of omniORB but this
cannot be a compass for me as Duncan mentioned previosly.
